A phase map of an agglomerated particle in a common lithium iron phosphate (LFP) battery electrode shows the charge distribution as it goes from 4% to 86%. FP refers to iron phosphate. Rice University scientists found that the FP phase spreads nonuniformly on an aggregate surface upon charging, rather than the expected even spread of lithium over the surface. The scale bar is 10 microns.

Figure 1: Bourns’ recently released IsoMOV hybrid protectors are designed to efficiently manage the current density in the MOV resulting in substantial surge current handling in a given size device. IsoMOV devices are rated to 125ºC with nominal surge ratings of 3 kA, 5 kA, or 8 kA, and are available with Maximum Continuous Operating Voltage ratings up to 555V – ideally suited for 480 V industrial power lines
